Deprecate :controller and :action path parameters

Allowing :controller and :action values to be specified via the path
in config/routes.rb has been an underlying cause of a number of issues
in Rails that have resulted in security releases. In light of this it's
better that controllers and actions are explicitly whitelisted rather
than trying to blacklist or sanitize 'bad' values.

- Addresses issue #12330
Overview
========
Cached postgres prepared statements become invalidated if the schema
changes in a way that it affects the returned result.
Examples:
- adding or removing a column then doing a 'SELECT *'
- removing the foo column then doing a 'SELECT bar.foo'
In normal operation this isn't a problem, we can rescue the error,
deallocate the prepared statement and re-issue the command.
However in PostgreSQL transactions, once any command fails, the
transaction becomes 'poisoned' and any subsequent commands will raise
InFailedSQLTransaction.
This includes DEALLOCATE statements, so the default deallocation
strategy instead of removing the cached prepared statement instead
raises InFailedSQLTransaction.
Why this is bad
===============
1. InFailedSQLTransaction is a fairly cryptic error and doesn't
communicate any useful information about what has actually gone wrong.
2. In the naive implementation the prepared statement never gets
deallocated - it stays alive for the length of the session taking up
memory on the postgres server.
3. It is unsafe to retry the transaction because the bad prepared
statement is still in the cache and we would see the exact same failure
repeated.
Solution
========
If we are outside a transaction we can continue to handle these failures
gracefully in the usual way.
Inside a transaction instead of issuing a DEALLOCATE command that will
certainly fail, we now raise
ActiveRecord::PreparedStatementCacheExpired.
This can be handled further up the stack, notably inside
TransactionManager#within_new_transaction. Here we can make sure to
first rollback the transaction, then safely issue DEALLOCATE statements
to invalidate the rest of the cached prepared statements.
This also allows the user (or some gem) the opportunity to catch this error and
voluntarily retry the transaction if a schema change causes the prepared
statement cache to become invalidated.
Because the outdated statement has been deallocated, we can expect the
transaction to succeed on the second try.

`OptimizedFileSystemResolver` (which most Rails apps use), but did not
implement the feature on the more generic `PathResolver`, which is often
used in tests etc.

When the `source_type` option is passed to a has_many through, the
resulting `Reflection` will be an instance of `PolymorphicReflection`
and not `ThroughReflection`, meaning that it will ignore the scopes that
it needs to apply from the through reflections. This adds an additional
delegation call to remedy this. I've been finding the reflection code
completely impenetrable lately, it could use some major love.

association when eager loading.
Previously, eager loading a `has_many :through` association with no
defined order would return the records in the natural order of the
database. Now, these records will be returned in the order that the
joining record is returned, in case there is a defined order there.

We only reference the Action Controller error classes by name in
ActionDispatch::ExceptionWrapper, so there is no need to explicitly
require them.
It drops a tiny coupling between Action Dispatch and Action Controller,
so it makes me feel warm inside. We still have a lot of others AC
requires in the AD code base, but here, we can save it.
